JAMES S. BROVN, OF PAWTUCKE'I, MASSACHUSETTS.

SPEEDER.

Specification of Letters Patent No. 16,463, dated January 27, 1857.

To all whom it may concern:

Be it known that I, JAMES S. BROWN, of Pawtucket, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in the Speeder (or Fly- Frame) for Roving or Spinning Cotton and other Fibrous Materials; and I hereby declare the following to be a true and exact description thereof, reference being had to the drawings herewith presented, which drawings constitute a part of said description, viz.:

Figure l represents so much of the machine as will be sulicient to show the application of my invention to the common fly frame or Speeder.

The nature of my improvement may be most readily understood by referring to the functions and operations of the Speeder.

This complex machine has long been adopted by all the most competent manufacturers as the most perfect in its operation of any yet used for preparing and winding the delicate rudiments of threads of cotton and wool called rovings.

The prime object of the machine is to prepare the material in such form and consistence that it can be spun with the greatest facility and uniformity. For this purpose it is requisite that the roving shall be not only uniform as to thickness, but also uniform as to the degree of twist and compression of all its parts. It is found that those rovings having a 'small degree of torsion spin more easily and more evenly than those which have more, or even less twist, and 1t is requisite that they should be wound closely and delicately on the bobbins in order to bear the handling with safety.

To enable others to make and use my improvements I proceed to describe its construction and use as follows: Having obtained the suitable movements to vibrate the bobbins up and down upon the spindle so as to lay `the several coils of roving evenly upon the bobbin, itis necessary to press lightly on every coil as it is wound on; by this means the slight compression given enables the bobbin to contain twice as much as can be put on by the Hier without pressure; this also enables the rovings to endure handling without being injured, and in order to use the bobbins without heads it is necessary to adjust the extent of each vibration shorter and shorter as the bobbin lls, so that each course of roving stops short of the extent of the one before it, producing the conical form of the end as seen on the full bobbin.

In Fig. l, E, represents the empty bobbin and F, represent-s the full one. When the bobbins are illed they are to be removed and in order to get them out of the flier the spindle must either be lowered down, or the fliers removed or the spindles be made shorter than is requisite to give the steady regular motion. All those devices have been tried, and the English fly frames are made with short fliers only attached by friction upon the upper part of the spindles in order to be removed while taking off the bobbins. Now the great objection to this plan is that the flier having no other support but the long unsteady spindle, can endure only half as much speed as is usually given to the American (long fliers), and produces consequently but half as much work in the given time.

By my improvement I am enabled to depress the spindles instantly down to their proper place of starting, and this by simply loosening a wheel by the screw (71%,) seen on the disk (D).

See Fig. l: (A) is the frame; (B,) is the flier board; (S,) is the rack shaft having a disk of metal (D,) which is fastened to its end and having two pinions (P P,) working in to the racks (r 7'). To these racks is attached a steprail ((1,) which raises the spindles (T T,) and with them the bobbins (E, and F).

Fig. 2 is a section of the disk (D) showing the cogwheel on the shaft (8,) driven by the pinion (P) on the shaft These shafts extend through the frame and have the wheel and pinion on the outside. Similar letters refer to corresponding parts in each gure. The two hooks (I-I and H,) shaded red are seen at Fig. 2 extending through the disk (D,) and hooked on to the flanch (J, J,) formed on the hub of the wheel (W). This wheel is loose on the shaft, but the disk (1),) is keyed fast to the shaft and the wheel is fastened by the fianch being forced up to against the flanch by these hooks and screws (m, and m,). At (2,) is seen a crooked stand or stopper, so placed on the frame as to arrest the descending of the spindles at the proper place by coming in contact with a knob (N,) on the disk.

Fig. 3, shows the wheel (W,) and its pinion (P,) having the disk removed in order to show the lanclriv (JQ. The disk and its l scribed for the purpose of enabling the opflanch covers and protects the Wheel and erator to remove the full bobbins and insert i l pinion. the empty ones in their place.

What I claim as my invention and desire JAMES S. BROWN. 5 to secure by Letters Patent is- Witnesses:
